   during its Warring-States period, 1467-1600.

2. WarringStatesJapan_diffusiondata_monadic.csv -- This is the data used for the monadic diffusion analysis in the article.

3. WarringStatesJapan_diffusiondata_dyadic.csv -- This is the data used for the dyadic diffusion analysis in the article. 

4. Introducing the Warring-States Japan Battle Data - Online Appendix.pdf -- This is the online appendix that accompanies
   the article.

5. Introducing the Warring-States Japan Battle Data - Data Analysis Replication File.R -- This is the R code needed to
   replicate the results of the analysis presented in the article and the online appendix.
